Question:
Honorable Shaykh, the questioner says: If one forgets to say the supplication for relieving oneself and does not remember it until after entering, is it prescribed for him to say it while inside the toilet?
Answer:
Yes, he says it, even if he does not remember it until after he has entered the toilet. It is said that there is no harm in that. In fact, some scholars derived from the apparent meaning of the hadith that he says it when he enters, as the Messenger (peace and blessings be upon him) said: "When one of you enters..." The word "enters" is in the past tense, meaning, yes.
